comboBoxAdv: images when using data-binding

[Philipp Gruber]

Hello,

I use a comboBoxAdv and fill it with data via data-binding:

BindingSource source = GetMySource();

comboBoxAdv1.DataSource = source;

This works fine but I like to show a image/icon in front of each element.

In the designer I set the "ImageList" property of the comboBox to an imageList with the images. I also set the "ShowImageInTextBox" and "ShowImagesInComboListBox" properties to true.

When I set the "ImageIndexes" of the comboBox items

comboBoxAdv1.ImageIndexes[index] = 0;

the image isn't shown. 

What do I have to do to show the images?

I found this post

where the answer to my question is a link to a sample. But unfortunately this is a dead link.

Thanks,

Phil

Hi Paul,

Thanks for your reply.

I had a look at the sample code but unfortunately it does not work 100% for me.

I use the comboBoxAdv control in a master-slave scenario where the combo box is the slave and gets filled dynamically (the bound data-source changes) depending on the selection in the master control.

The code-sample sets the images during the Load event handling, so it is set only one time before the form is displayed and when my data-source changes the icons are not displayed any longer. 

When I try to use the init code:

((System.ComponentModel.ISupportInitialize)(m_SourceComboBox)).BeginInit();

comboBoxAdv1.ItemsImageIndexes.Add(new ComboBoxAdv.ImageIndexItem(comboBoxAdv1, "XYZ", 1));

((System.ComponentModel.ISupportInitialize)(m_SourceComboBox)).EndInit();
 in a corresponding event-handler (e.g masterControl.SelectedItemChanged) that the icons are updated each time the source of the comboBoxAdv changes it doesn't work.
Is there any change to set the images in a way that it fits into my scenario?

Thanks,
Phil

Hi Phil,

Thanks for the update.

When you insert a row and update the datasource it is needed to reinitialize the images to the corresponding rows. Please have the sample according to your requirement from the below link.
